l PUMP-REGULATING` MECHANISM.

SPECIFICATION forming part of Letters Patent No. 737,332, dated August25, 1903.

Application ledMarch 28 1902 To all whom it may concern:

Be it known that I, WORTHY CHANNING BUCKNAM, a citizen of the UnitedStates, residing at Geneva, in the county of Ashtabula and State ofOhio, have invented a certain new and useful Improvement inPump-Regulating Mechanism, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings.

The object of this invention is to provide means for varying thedelivery of a pumpl while it is in operation, so that it may supplyfluid according to the varying demands upon it. My pump is especiallydesigned for feeding the water to the boiler of a steam-automobile, andthe adjustable delivery, accomplished by the varying the stroke of thepump, obviates the necessity of by-pass valves to prevent the unduefeeding of the boiler.

To this end the invention consists of a pump, mechanism for driving it,and means for varying the stroke of the pump while it is in operation.The particular embodiment of this, hereinafter shown and described, isalso comprehended within my invention.

The drawings clearly illustrate VVmy invention as applied to a pumpsuitable for automobile use, Figure l being a side elevation, and Fig. 2a bottom plan.

In the drawings, A A represent a pair of pumps operated by thereciprocation of the common piston-rod B, which passes into thepump-chambers through stuffing-boxes C C,

or frame D. The rod B, whose reciprocation causes the pumping action,has a collar b, from which project pins b'. These pins take into thebifurcated ends of the arms E, Secured to a rock-shaft F. On the outerend of the shaft is secured the lever G, the bifurcated end g of whichis adapted to take around a pin (not shown) from some reciprocating partof the machinery-as theoross-head Of the engine. The Oscillation of vthelever G thus caused operates thepump. Now I journal the rook-shaft F ina pair of levers H and H', which are secured to a shaft-K, journaledserial No. 100,452. (No man.)

in the depending end d of the yoke-frame D. A

rook-shaft F, and thusvarying theI stroke of the pump.,

In operation when the engine isA running,-

Oscillating the lever Gand driving the pump,

if too much water is being delivered to the boiler the handle Nis turnedin the direction to lower the nut J, thus bringing the rockshaft Fnearer the pins b and shortening the plished during the runningof thevehicle, as

circumstances require.

I claim- 1. In combination, a frame, a pair of alined pumps carriedthereby, a common piston-rod for said pumps, a pair of links pivoted tosaid frame, a rock-shaft carried by the other ends of said links, one ofsaid links being extended in the opposite `direction from its pivot,thereby forming a lever, means engaging said lever at the end thereoffor shifting it to change the position of said rock-shaft, an armcarried by the rock-shaft and movably engaging a pin carried by thepiston, and another arm carried by the rock-shaft for actuating the armfirst mentioned, substantially as described.

2. In combination, aframe, a pair of alined pumps carried thereby, acommon piston-rod for said pumps, a pair of links pivoted to said frame,a rock-shaft carried by the other ends of said links, one'of said linksbeing extended by forming a lever, a nut loosely carried by the endthereof and provided with a threaded 2 @smeg In testimony whereof Ihereunto ax my opening, zt soew rotatably mounted, for ensglmturo in thepresence of two witnesses.
